CHRIsTY BROWN; OF WILMETTE', ILLINOIS, AssIGNOR. To AMERICAN CAR ROOF v COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

Cnn-:soon

To all whom t may concern.' A Be it known that I, CHRIs'rrBRowN, a citizen of the United States, residing at y lVilmette, in the county of Cook and State of llli'nois, have invented certain newf'and useful Improvements in Car-Roofs, of which -the following is a specification.

of a single thickness of metal, have the objectionthat there is a tendency for moisture and frost to collect on their under surface, which is likely, especially under the vibration ofthe car in traveling, and under the heat ofthe sun on the meta-l, to drip .l5 on the lading, giving it an unsightly appearance, ifv not actually damaging the oods. 1

It has ybeen proposed heretofore to ventilate such a roof structure in an'attempt 20. to overcome this moisturecollecting or condensing propensity, but I have found that vit is a much, better plan to line the roof with a heat-insulating and, preferably, moisture-absorbing material, such, vfor example,

. 2,5 as wood.

'A further object lof the invention is to so associate such wood'lining with the metal.4

roof elements that it .may be readily put in and-retained in place without bolts-Or rivets '3Q passing through` the boards, and, in..` the preferred embodiment ofthe invention,-

these boards extend lengthwise the .car only from carline to carlinel and are held in place directly by the metal roof-sheets, which are in turn supported by the boards.l

With these and various other objects in View, in order that thoseskilled in the art may understand the invention, I have illusvtrated adesirableembodiment of the same in the accompanying drawings, throughout the various views of which 'like reference 'characters refer to the same parts.

' In these drawings, Figure 1 is a cross- 'section through the roof structure; Fig. 2.

is an enlarged fragmentary7 longitudinal section through Vthe roof Onq line 2 2 of Fig. 1;

Fig. 3' is an enlarged fragmentary crosssection of the portion .of the roof adjacent to the side-wall; and Fig. 4 is a horizontal sectionon line 4-4 of Fig. 3.

As is customary in structures of this general character, at the top of each side-wall 10 of.the `carbody, there is a .longitudinal Z-bar side-plate 11 .having an\loutwardly extended lower flange, and an inwardly-pro- Speciication of Letters Patent.

jecting upper flange. The carlines 12 are of channel form with outstanding top, marginalv vflanges 13, 13, the carlines preferably extending' from' sidelwall to side-wall and being securedfto the top flanges of the sideplates 11 by means of pressed-metal shaped brackets 14 conforming to the under sur# faces of the end portions of the carlines and riveted thereto. An eave strip l5 is located above each side-plate 11 and has a downturned outer flange 16 and an inner inclined flange 17 disposed between the downwardly curved end of the carline and the adjacent portion of the "bracket That is tosay, the

carline, including its side-walls and its outwardly-projecting flanges 13 is bent down at the end, as is clearly shown in Figg', and each flange 13 at'any suitable point, but preferably above. the side-plate, is pressed to form al boss or lug 18, for a purpose hereinafter indicated.

The 'lining of the roof comprises a series"v of boards, onother suitable members, 19, 19,

disposed longitudinally of the car, resting upon the carlineiflanges 13, and extending only from carline to carline, as shown in Fig. 2, lwhich permits the employment .of relatively inexpensive lumber for this purpose. The outermost board at eachV side of the car is prevented from displacement by means of the stops 18, 18, and the other boards are merely laid in place, none of them having anyfastening-means, such as nails,'bolts, rivets,'orthe like, and, by reai I son of this construction the parts of the roof maybe quickly and. easily assembled.

f The sheet-metal roof-plates 20 extend lacross the full width of the car `and laterally tions of the carlines.

Each carline is provided with'a cap or weather-strip 22 longitudinally depressed at 23, providing a rib extending between the `roof-plate flanges 21 of adjacent plates and at each .side of the car each cap-strip has a depending flat ear 24 secured to the side` vperforms the function of a heat insulatoi and a moisture abosrbing element, but it also constitutes a support for the roofsheets, assisting in carrying the load imposed on the latter. This-wooden lining, owing to its insulating propensities, tends to prevent the formation of moisture and frost on 'the inner surface of the metal portions ol" the roof, but if such moisture accumulates or such frost melts it will act .as an absorbent material, preventing the moisture from dripping and injuring the lading. It should also be noticed that those portions of the roof unprovided with the lining are composed of 4two metal parts, carline and cap-strip, separated from one another suiiciently to provide an air space which compensates for the absence of the lining at those places.

The structure presented herein represents merely a desirable way of incorporating the invention in practical form, but it is not to be understood that the invention is limited and restricted to the precise and exact structural features illustrated and described, be-v cause these may be modified withinl comparatively .wide limits without departure rom the substance of the invention as defined by the claims.

I claim r- 1. In a railway-carfroof construction of the 'character described, the combination of metal carlines, heat-insulating members disposed lengthwise of the car, resting on and supported by said carlines, and each extending only from one carline to the next, said heat-insulating members unitedly forming .t roof lining, flanged, metal roof-sheets -above said members and'having their flanges eX- tended downwardly across the ends ot said members, the latter being restrained from lengthwise movement solely by such flanges, substantially as described.

2. In a railway-car roof construction of the character described, the combination-olf channel metal carlines disposed trough side upward and having oppositely-extended anges at their top edges, boards disposed lengthwise of the car resting on and supported by said carline flanges, and each extending only from one carline to the next, and metal roofsheets covering said boards and having marginal flanges projecting into the troughs of said carlines and coperating with the ends of the boards to prevent substantial displacement'otl the latter, substantially as described.

3. In a railway-car roof construction of the character described, the combination ot' channel metal carlines, disposed trough side upward and having oppositely-extended ianges attheir top edges, equipped with stops near their ends, boards disposed lengthwise of the carresting on and supported byl said carline anges and each extending'only from one carline to the next, the outermost boards bearing against said stops, and metal roof-sheets covering said boards and having marginal Hanges projecting into the troughs of said carlines and cooperating with the boards to prevent substantial displacement of the latter, substantially as described. l

4. In a railway-car roof construction of the character described, thecombination ot' flanged channelcarlines, disposed trough side upward, Wooden boards supported on said carline flanges, metal roof-plates hav ing marginal flanges holding said boards against substantial.displacement and projecting downwardly into the carline troughs, and cap strips above said carlines having portions extended between the roof-plate liiianges and holding them separated, substantially as described.
